Spaghetti carbonara

Yesterday my sister and I made dinner. we made our most favorite pasta, yess carbonara. I'm personally in love with carbonara sauce, well who doesn't?? we usually make fettuccine carbonara but it's been a long time since I ate spaghetti so yeah..
I used to make this with another recipe, but the result was never like what I'd expected. so one day I went to google a recipe and voila! I found this recipe and after first try I couldn't believe myself because it tasted like real carbonara I almost cried, jk. sooo I always use this recipe everytime I make carbonara!

Here's the recipe that I found online, I forgot the source i'm sorry.

Ingredients
4-5 smoked beef, sliced
3 spring onions, diced, or 1 medium onion, sliced
1 x 300 mL cream
1-2 teaspoons crushed garlic
1 x 200 gr punnet sliced mushroom
1 egg, whisked

p.s: it doesn't have to be always fettuccine you can eat it with other pastas whichever you like.
and this recipe is for 4 servings


Method
1. In a lightly oiled frypan, saute garlic on a medium heat.
2. Add smoked beef, mushrooms and onions, and cook for 2 minutes.
